Abstract: An operator selectable performance control system for an electric vehicle, is provided. In various embodiments, the system includes a motor structured and operable to provide motive power and regenerative braking forces to the vehicle and a mechanical brake assembly structured and operable to exert mechanical braking forces to the vehicle. The system additionally includes a controller operable to control the application of motive power and regenerative braking forces of the motor. The system further includes an operator selectable switch structured and operable to changeably select one of a plurality of vehicle performance routines executable by the controller for affecting maximum vehicle speed and an amount of regenerative braking implemented during vehicle operation.

Abstract: The present invention provides a system for compensating understeer and oversteer in a vehicle having a steer by wire system. The system includes a driver interface system, a sensor system, a controller, and a road wheel steering actuation system. The driver interface system receives steering input from the driver. The sensor system senses the steering input and generates a steering control signal that is received by the controller. The controller determines if an understeer or oversteer condition exists and generates an appropriate steering assist signal that is then communicated to the road wheel steering actuation system. In response to the steering assist signal, the road wheel steering actuation system adjusts the road wheel angle to compensate for the understeer or oversteer condition.
